Abstract The past several years have witnessed the rapid development in effectively transforming randomly distributed water kinetic energy into electrical energy, especially triggered by emergence of droplet‐based electricity generators (DEG). Despite this, it still suffers from relatively low average power density, which is also achieved at cost long charging time, time to reach stable and saturated surface charge density either through continuous droplet impingement or precharging. Although harvested per DEG remains as dominant metric, ultrahigh instantaneous output short are equally important some specialized applications such luminescence. Here, we conduct systematical modeling optimization build link between hydrodynamic systems, enables us determine tailoring parameters dielectric layer thickness, ion concentration, external load. We envision that this strategy achieving well shortening would provide insights design routes for harvesting.
